  • 3D print a case mold to make duplicate mold parts

    It can take several weeks for plaster to dry to the point where it works effectively with slip. I made these in the summer, so I left them in the sun in dry heat to speed up the process (they were useable after a few days). Another shortcut is to put your molds in an oven at, say, 150°F for many hours, but I would caution against setting the temperature higher. If you accidentally boil the water that's trying to escape, it will cause the mold to crack. A third option is to look up instructions for how to build a dehumidifier/dryer. For that route, keep in mind the shelves need to be quite strong to hold large plater parts. Also, try not to let your space heaset fire to anything if you stick a space heater in a small space.
